Don't 'bee' worried: Researcher says endangered bumblebee populations will rise again

The rusty patched bumblebee, Bombus affinis, recently became the first U.S. bumblebee species to be placed on the endangered species list, but a Kansas State University entomologist says bumblebee endangerment is nothing to be bugged about.

Jeff Whitworth, associate professor of entomology, said bumblebees are not headed for extinction. However, their populations have decreased in some states, so inclusion in the U.S. Fish and Wildlife Service's Federal Register may help keep them and other bee species at healthy population levels.

"Being on the endangered species list is not bad," Whitworth said. "It helps people have more awareness and information about bees, and it leads to regulations and programs that help keep bees alive."

Some people fear bees because they occasionally sting, but Whitworth said bees will not bother people if people do not bother them. He said bees are beneficial because they pollinate flowers, citrus crops and vegetables, and they serve as food sources for other insects, birds and fish.

"If bees go away, other organisms go away, too," Whitworth said. "It's a domino effect."

Bee declines are attributed to a variety of factors, including parasites, pesticides and urbanization, as well as fungal, bacterial and viral diseases. They also are affected by the introduction of non-native plant species and natural disasters, from floods to drought.

Whitworth said bee populations could be protected by areas of native plants and grasses, conservation-focused farming and gardening methods, and the hobby of beekeeping, which is growing in both rural and urban areas. These protective practices help turn one's backyard -- even a little piece of it -- into a natural ecosystem.

Researchers find rare bee feared headed for extinction

Rusty patched bumble bees were once a common sight, flitting from flower to flower to sip nectar and transfer pollen. But that species of bee had not been seen in the eastern United States for five years, and researchers feared that one of nature's most efficient pollinators was headed for extinction.

This summer, though, a research team led by a University of Virginia professor and two members of the Smithsonian Conservation Biology Institute spotted a rusty patched bumble bee at Sky Meadows State Park in Delaplane, Virginia. It was only one worker bee from the rusty patched species, out of the nearly 35,000 bees belonging to 126 species collected and examined in the study, but its identification raises the possibility that this extremely rare species may be hanging on.

"In 20 years of studying bees, I have never seen a rusty patched," said T'ai Roulston, research associate professor in the College of Arts & Sciences' Department of Environmental Sciences and a member of the research team. "Where there is a worker bee, there is a colony and maybe more than one. As they've gone underground for the winter, we can actively look for the colony next spring, study them and what might be affecting the species.
